FURNACE.

Application filed July 3,

To all whom it may concern:

Be it known that I, JosnPH T. WENSIULIS, a citizen of Russia, residing in the borough of Queens, county of Queens, city and State of New York, have invented an Improvement in Furnaces, of which the following is a specification.

Heretofore, in the use of furnaces of the type to which this invention relates, difliculty has been experienced in the burning out of the top or the roof of the furnace as well as the burning of the casings defining the openings for the doors and this has made it necessary to more or less frequently replace the entire cover or roof as well as the casings defining the openings for the doors, and the primary object of my invention is the provision of a furnace in which the cover or roof is made in sections independently secured in place and separately removable so that in the event of any portion of the cover burning out one or. more sections maybe removed and replaced without replacing. the entire cover, thereby not only afiecting a saving in the labor involved but a'material saving in the cost of the operation of the furnace. The construc tion is also such that the metallic parts forming the casings for defining the openings for the doors are lined with suitable" fire brick or other material to protect these metal casings. The invention also includes a novel form of base and support for the bottom or floor of the furnace as well as means for operating the furnace doors, all of which will be hereinafter more particularly described.

In the drawing:

nace made in accordance with this invention comprises a base which is preferably made in sections indicated respectively at 1O, 11 and 12. It will be understood that while I have illustrated the base as made of three sections it may be composed of any desired number of sections depending upon the size of the furnace. Supported upon the base are the side and end walls of the furnace. The side walls are preferably divided into upper and lower sections. The lower side wall sections are indicated at 13 and lt and respectively are secured to the base by series of bolts 15 and 16 which pass through flanges on the lower side walls and the base. The upper side wall sections are indicated at 17 and 18 and these are secured to the lower side wall sections by bolts 19 and 20 which pass through the upper flanges of the lower side wall sections and the lower flanges of the upper'side wall sections. The end sections are indicated at 21 and 22, and these sections are secured to the side wall sections bybolts 23 and 24 which pass through the end flanges of the side sections and the side flanges of the end sections so that the side and end sections of the furnace which may be made of any suitable material are secured to each other and to the base.

The bottom of the furnace as illustrated preferably comprises a'series of cross rails 25 having end portions or extremities 26 turned at right angles thereto as indicated at 27 and secured to the under sides of the lower flanges of the lower side sections 13 by bolts 28 or otherwise. The bottom of the furnace also includes a series of longitudinal rails 29 extending at right angles to the cross rails 25 and suitably spaced as indi- -cated at 30 so that upon this bottom structure the floor of the furnace maybe, built.

The end sections of the furnace are provided with openings indicated at 31 and 32 for conveying thereto the material to be smelted in the furnace. The body'of the furnace is lined with fire brick, asbestos composition or other similar material so as to be provided with a fioor indicated at 33 and sides 34 and 35 and ends 36, the end lining sections 36 being so constructed as indicated at 37 in Figs. 1 and 2 of the drawing as to extend over the edges of the frame casings defining the outline for the doors in order to protect the metal frame of the furnace at these particular places. In a suitable posilowered and maintained in either the low-, ered and closed position or'the raised and in support flanges 41. Depending from the body member of each cover section there are also retainer flanges l2, and 1n order to strengthen each cover section the same may be provided exteriorly and longitudinally with a rib 4E3. Interiorly each cover section is fitted with a series of bricks er which are maintained in position between the retaining flanges 42. These cover sections are adapted to extend across the furnace and to be supported upon the upper edges of the upper side members with the flanges ll resting upon the upper flanges of the side members through which suitable bolts 45 are passed in .order to secure each section of the cover in its position 1n the furnace.

As illustrated in Fig. 4 the upper portions of the side linings are constructed to receive the retainer flanges 4:2 in such a manner that by these linings as well as by the bricks 44 the retainer flanges are entirely concealed in the lining of the furnace. It will also be apparent that with the covers thus constructed any one or more of the covers may be separately removed and replaced without disturbing the others, as each of these cover sections is secured in' position independently of the others. i

The openings 31 and 32in the ends of the furnace are provided with doors 46 and 47 respectively which may be lined with fire brick &8 or other suitable material and made to slide in suitable guides provided for this purpose, these doors being made to rise and fall in opening and closing the furnace. For this purpose, as illustrated, the upper edge of each door may be fitted with eyes 49 to which is secured a yoke 50 connected by a link 51 to a lever 52 as illustrated in Figs.

Also as'illus l, 2 and def the drawing. t'ratedin these figures of the'drawing, the

furnace body may be fitted with a bracketv 53 m which the lever 52 is pivotally mounted and the lever 52 connected-by a rod or chain 54 with a suitable weight 55 by means of which parts the 'doors'may be raised and open position.

' By referring to Fig. 7 it will be seen that 'I'may' also employ a different form of construction for operating the furnace doors.

flhisi nclu'cles brackets 56 and 57 mounted on the sides of the furnace and connected by a cross bar 58in which there are mounted pulleys 59 and 60, a chain or cord 61 passthe furnace doors, while at the opposite end this chain 61 is connected to a weight 62 by a clevis 62' in which there is also pivotally connected, as indicated at 66,:a lever 63. In one end of the lever 63 there is a slot 64 adapted to receive a pin 65 fixed in the frame of the furnace so that by the operation of the lever 63 the weight'may be raised and lowered to lower and raise the furnace doors and thus close and open the same.

I claim asmy invention:

1. A furnace comprising a base, side and end walls rising therefrom, anda multiple section top, each section of the top consisting of an arched bodyportion having integral retaining and supporting flanges at the ends thereof, a lining extending between and held in position by the saidretaining said walls in one end of'which there is an opening, a door for normally closing the sald opening, a llning withln the said walls extending outwardly through the said opening to protect that portion of the wall clefining the opening, and means for operating the said door. 5 1

d. A furnace comprising a base, walls rising" therefrom, 21} top extending across the said walls in one end of which there is an opening, a* door for. normally closing the said opening, a lining :within the said walls extending outwardly through the said opening to prOtect'thatLportion of the wall defining the opening, a! bracketffixed in one of the said walls, a lever pivotally iio I mounted in the said bracket, a connection V 7 between one end of the lever and the said door, and means for operating theopposite end of the said lever to raise and-lower the said door and thereby open andclose the opening in the wall.'

5.. A furnace comprising .a base having a plurality of sections, side walls, end walls, the said walls rising from 'the'said' base, a

top extending between and secured to the said side walls, and a bottom consisting of a plurality Iof cross bars extending between the said side wallsan d secured thereto, and a plurality ofspaced longitudinal bars resting upon the said section of the base to support the floor of the furnace.

6. A furnace comprising a base having a' plurality of spaced sections, side walls, end walls, said walls rising fronithe base, a top extending across and secured to the said side Walls, and a bottom consisting of a plurality of cross bars having their extremside walls bars restin and a plurality of longitudinal g upon the sections of the base or supporting the floor of the furnace.

Signed by me this 7th day of May, 1920. 15
